Evaluation of Bipolar Pb-Acid Batteries for Aircraft Applications

摘要

An effort was undertaken by WL/POOB to evaluate bipolar lead-acid (Pb-Acid)batteries for high power density, high voltage applications such as the more electric aircraft (MEA). This technology is also being studied for use as the power source for electric vehicles. These batteries were delivered under developmental programs with Pinnacle Research Institute (PRI) and Johnson Controls, Inc. (JCI). This report describes the results of the evaluations performed at WL/POOB. The bipolar Pb-Acid technology was chosen as a candidate for the MEA due to its inherently high power density and relatively compact size. Results of these contracts and the WL/POOB evaluation task clearly show that much developmental work remains to be done if this technology is to be used.
